Members of Nellis Air Force Base run with the American flag Sept. 11, 2014, during the Old Glory Challenge at Nellis AFB, Nev. During the challenge, participants were charged with continuously running with the flag in 30-minute increments from 6:30 a.m. to 4:30 p.m. The goal of the event was to help participants remember the events of 9/11, honor those lost in defending freedom and tell the story of all who serve in defense of freedom.
